I will be explaining what happens to the female body changes during sex in 4 phases.
First phase
The first phase is that of excitement. In this, your heart rate starts to increase and your pulse becomes quicker because your heart rate is going faster. The oxygen requirement in your lungs increases because of which you start breathing heavier and heavier so as to take in more oxygen. Small blood vessels and capillaries along the surface of your skin also start to dilate because of which your skin appears red, flushed and glowing. Apart from this there is an increased blood flow to the secondary sexual organs such as the breasts and the genitals. What happens in the genital regions?
- Your clitoris swells up and it becomes increasingly more and more sensitive. Your vagina also swells up and it almost changes its color because of the accumulated engaged blood vessels and it becomes dark purple in color.
- Your breasts and your nipples become erect. Breasts may temporarily seem bigger (can increase up to 25%) than they normally are because of the engorged and dilated blood vessels.
Phase two
Phase two is phase of plateau. All of these intense feelings start to build up and your vagina also starts to lubricate itself with a natural fluid expecting penetration. Apart from this, the muscles in your entire body become really tensed while your heart rate, your breathing and your BP also continuously starts to rise.
Phase three
Phase three is the phase of climax where your body reaches its peak levels of excitement. There is an intense sense of release and after that it feels like your muscles, your vaginal muscles are contracting and relaxing very vigorously. After this, there is a surge in happy hormones (that is your oxytocin) levels. Oxytocin is the hormone related to happiness and which also promotes bonding which is why you tend to feel attached to the person after having intercourse.
Last phase
The last phase which is the phase of resolution. Resolution, meaning all the parts of your body go back to their state pre-sex which means your heart rate, your pulse, your BP and your breathing starts to slowly reduce and come back to normal. Your vaginal muscles go back to their normal state, your breasts and nipples go back to their normal state. You may feel a sense of relaxation or you may feel exhausted and tired and may go to sleep. This point is very important to know because this phase means that all the changes that happen during intercourse are temporary and within few minutes post orgasm everything returns back to normal.
